A patient diagnosed with nonscalp seborrheic dermatitis will be consented into the study and given instructions on the petroleum treatment. This includes wetting the affected area, blotting dry, and then applying petrolatum to the area before bedtime. This regimen is to be followed every other night until symptoms diminish. The patient will come back to the office for follow-up at one week, two weeks, and four weeks after treatment begins to see the outcome. Pictures will be taken at each encounter and used to measure progress through one mm graphs. Patients will not be identifiable in these pictures, and they will be labeled with the patient's given ID number.
